An object is to reduce changes in mechanical properties of a gas turbine blade base material during repair or regeneration of a gas turbine blade. For this purpose, a gas turbine blade after being operated is washed by being immersed into a strong alkaline washing solution, and the gas turbine blade after being washed with the strong alkaline washing solution is washed with water. The gas turbine blade after being washed with water is then washed by being immersed into a weak acid washing solution, and the gas turbine blade after being washed with the weak acid washing solution is subjected to heat treatment. The gas turbine blade after the heat treatment is then immersed into a strong acid washing solution, whereby the coating formed on the surface of the gas turbine blade is removed.

In a metal film production apparatus, a copper plate member is etched with a Clgas plasma within a chamber to form a precursor comprising a Cu component and a Clgas; and the temperatures of the copper plate member and a substrate and a difference between their temperatures are controlled as predetermined, to deposit the Cu component of the precursor on the substrate, thereby forming a film of Cu. In this apparatus, Cl* is formed in an excitation chamber of a passage communicating with the interior of the chamber to flow a Clgas, and the Cl* is supplied into the chamber to withdraw a Clgas from the precursor adsorbed onto the substrate, thereby promoting a Cu film formation reaction. The apparatus has a high film formation speed, can use an inexpensive starting material, and can minimize impurities remaining in the film.

This invention relates to a spray coating powder material which, when applied to gas turbines using a crude low-quality fuel oil as fuel, has sufficiently higher corrosion resistance to sulfur, vanadium, sodium and other substances that accelerate corrosion in a high-temperature service environment, than conventional materials such as Ni-50 Cr and MCrAlY materials, as well as high-temperature components coated therewith. Specifically, this invention relates to a spray coating powder material comprising, on a weight percentage basis, greater than 45% and up to 60% of chromium, 5 to 15% of aluminum, 0.5 to 10% of zirconium, and the balance comprising cobalt or iron, or both, and incidental impurities, as well as high-temperature components coated therewith. This material can yield a sprayed coating having high corrosion resistance to sulfur, vanadium, sodium and other substances that accelerate corrosion in a high-temperature service environment.
